Why Create Sustainable Neighborhoods?
“The private vehicle is the largest contributor to a household’s carbon footprint – using public
transportation reduces household carbon emissions”

The Currie Barracks Project
A community that:– Supports new approaches to moving around– Enables people to live in close proximity to their work– Embraces its history– Has an “inner city” character throughout
Creating energy and resource efficient buildings and communities!
– Has an inner city character throughout– Boasts a great system of parks, streets and pathwaysA vibrant, mixed-use, sustainable community on the edge of the inner city where people can live, learn, work and play.

Green Tips for Green Communities
1. Dense transportation network – lots of intersections either roads or walkways– good public transit coverage
2. Few major roads, lots of minor roads– Site exit every 250 metres
3 Small lots - dense communities
Creating energy and resource efficient buildings and communities!
3. Small lots - dense communities– 7 dwellings per acre, – 12 dwellings per acre near public transit
4. Minimize area for parking lots– Parking on-street, underground or in parking structures
5. Lots of public spaces– Connect with trails– Preserve existing natural areas
Green Tips for Green Communities
6. Mixed use developments– Include commercial, retail and other uses
7. Diverse housing types– Range of types and values
8. Small setbacks and garages to back of lotE lk bl iti d th t t
